# OpenGLDevice::CreateFence
|
||
|
||
```cpp
|
||
RHIFence* CreateFence(const FenceDesc& desc) override
|
||
```
|
||
|
||
创建同步栅栏对象。
|
||
|
||
## 详细描述
|
||
|
||
创建用于 GPU/CPU 同步的栅栏对象。
|
||
|
||
### FenceDesc 字段
|
||
|
||
| 字段 | 描述 |
|
||
|------|------|
|
||
| `initialValue` | 初始值（0=未 signaled, >0=signaled） |
|
||
|
||
### 行为
|
||
|
||
- `initialValue > 0`: 创建时栅栏处于 signaled 状态
|
||
- `initialValue == 0`: 创建时栅栏处于未 signaled 状态
|
||
|
||
## 参数
|
||
|
||
- `desc` - 栅栏描述符
|
||
|
||
## 返回值
|
||
|
||
`RHIFence*` - 创建的栅栏指针
|
||
|
||
## 注意事项
|
||
|
||
- 返回的栅栏对象归调用者所有，需自行管理生命周期
|
||
- 栅栏用于同步 GPU 命令执行和 CPU 代码执行
|
||
|
||
## 示例
|
||
|
||
```cpp
|
||
FenceDesc fenceDesc;
|
||
fenceDesc.initialValue = 0;
|
||
|
||
RHIFence* fence = device.CreateFence(fenceDesc);
|
||
|
||
// 等待栅栏
|
||
while (!fence->IsSignaled()) {
|
||
// 等待或做其他工作
|
||
}
|
||
|
||
// GPU 命令完成，栅栏 signaled
|
||
```
